SPINNING- MACHINE.

SPECIFICATION forming part of Letters Patent No. 246,470, dated August30, 1881.

Application filed April 27, 1881.

To all whom it may concern:

Be it known that I, RICHARD B. DALY, of Newton, county of Middlesex,State of Massachusetts, have invented an Improvement inSpinning-Machines, of which the following description, in connectionwith the accompanying drawings, is a specification.

This invention in spinning-machines relates to that class of machinesknown as speeders, and has for its object to secure steadiness ofrotation and facilitate doffing, and is an improvement on the apparatusshown in my application No. 29,961, filed April 4,1881, to whichreference may be had.

My invention consists in a spindle having a bobbin-driving tubeconnected with it above the foot-step rail, so as to be raised andlowered on the spindle by the lifting or traverse rail as the said tubeis rotated by the spindle, the said tube sliding between the spindle andthe neck of the flier-gear. The bobbin in this my improved machine issupported internally by the upper portion of the bobbin-driving tube.The length of the spindle above the flier-neck is such that thereciprocating tube will be steadied by the spindle substantially up to apoint opposite the flier-presser, and so thatthe tube may besufficientlylowered thereon to permit the bobbin to be doffed as freelyas in a ringspinning frame.

Figure 1 represents, in elevation and partial Section, asuffieientportion of a speeder to illustrate my invention; and Fig. 2,an enlarged sectional detail of the spindle with a modified form oftube, the parts being broken out to save space on the'drawings.

The mechanism herein shown to rotate the spindle a, flier-gear I), andflier c are all as usual, so need not be herein further described.

The foot-step rail d, containing the spindlestep d, is fixed, as arealso the bolster-rail d and the top rail, (1 which receives the usualhollow nose of the flier c.

The neck of theflier-gear-b is extended down through the bolster-bearingb and is sufflcient-ly large in diameter to receive the bobbin-drivingtube 6 between it and the spindle, as represented in section, Fig. 1.

The spindle is grooved longitudinally, as at 2, to receive a key, 3,within the tube 6, so that the tube may be rotated by, yet bereciprocated on, the spindle by the rising and i'all- (No model.)

ing traverse-rail, actuated in any usual manner, upon which the lowerend of the tube rests.

The rotating spindle has its upper end extended up into the flier to apoint at or near or a littlebelow the presser-flierg,and the tube isextended,as herein shown, alittle above the top of the spindle when thetube isin its lowest position, as in Fig. 1.

The tube has a collar, 9, provided with a bobbin-engaging projection, h,of any usual shape, to enter the usual notch at the lower end of thebobbin 5. This tube may be made in one piece, as in Fig. 1, or twopieces, as in Fig. 2. If in two pieces, the upper piece may be a littlelarger in diameter internally than the lower piece, to thus lessenfriction on the spindle. In practice the spindle will be extended intothe flier above the flier-gear for a distance substantially equal to thelength of traverse, so that the part of the tube 6 below the collar 9will be guided firmly and steadied by the spindle in all positions ofthe tube and traverse-rail. When the tube is lowered, as in Fig. 1, thebobbin may be doffed therefrom as readily as in ring-spinning, and thatwithout the removal of a nut, pin, or bolt. The upper end of the tubemay be covered to prevent entrance of dirt. Any portion of the side ofthe tube where surrounded by the bobbin may be provided with anoil-hole, as shown in black at 76, Fig. 2. Oil may be introduced intothe tube by removing the bobbin.

I claim- The bolster-rail, flier, and connected fliergear I), having itsneck extended into the bolster-rail, the traverse-rail, and tube 0,moved thereby, extended upward through the fliergear, combined with thetube-steadying spindle extended up into the flier for a distancesubstantially equal to the length of the traverse of the tube, the topof the spindle terminating at a point substantially opposite theflier-presser, the combination being and operating all substantially asset forth.

In testimony WhereofI have signed my name to this specification in thepresence of two subscribing witnesses.
